It has been suggested that perception of visceral changes, and cognitive reactions to such changes, may be important for triggering panic attacks. It remains to be determined, however, whether people with panic attacks are actually characterized by enhanced perceptual acuity for interoceptive stimuli. The purpose of this study was to explore the relationship between panic attacks and awareness for cardiac sensations using an objective heartbeat discrimination procedure. Twenty panickers and 20 nonpanickers were given 60 trials of the Whitehead heartbeat discrimination procedure. Thirty trials were given during rest and 30 following hyperventilation. Results indicated that panic attacks were not related to enhanced interoceptive acuity for cardiac sensations, either at rest or following hyperventilation. These results are discussed in terms of their relevance to cognitive models of panic.
有人认为，对内脏变化的感知以及对这种变化的认知反应，可能对引发惊恐发作很重要。然而，惊恐发作的人是否实际上具有对内感受性刺激增强的感知敏锐度，仍有待确定。本研究的目的是使用客观的心跳辨别程序来探索惊恐发作与对心脏感觉的觉察之间的关系。20名惊恐症患者和20名非惊恐症患者接受了60次怀特黑德心跳辨别程序测试。其中30次测试在休息时进行，30次在过度换气后进行。结果表明，无论是在休息时还是在过度换气后，惊恐发作与对心脏感觉的内感受敏锐度增强均无关。将根据这些结果与惊恐的认知模型的相关性进行讨论。
